Advantages

Autumn shoulder season means 40-60% fewer crowds at major attractions like Machu Picchu and Torres del Paine, with accommodation prices dropping 25-35% from peak season
Perfect hiking weather in Patagonia with stable conditions, clear mountain views, and comfortable temperatures of 15-20°C (59-68°F) during the day
Harvest season in wine regions - Mendoza and Chilean valleys offer grape picking experiences and fresh wine tastings at 30% lower prices than summer
Amazon basin enters dry season with lower water levels making wildlife viewing easier and reducing mosquito populations by up to 70%

Considerations

Patagonian days are getting shorter with only 10-11 hours of daylight, limiting outdoor activity time and requiring early starts for full-day excursions
Beach destinations along Brazilian and Colombian coasts enter cooler, windier conditions with water temperatures dropping to 18-22°C (64-72°F)
Some high-altitude passes in Bolivia and Peru may experience early snow, potentially closing roads to remote areas like Salar de Uyuni's northern routes

Best Activities in April

Essential Tips

What to Pack

Layering system essential - temperatures vary 15-20°C (27-36°F) between day/night, pack merino wool base layers and lightweight fleece

Waterproof hiking boots rated for rocky terrain - Andean trails require ankle support on loose scree and wet morning conditions

SPF 50+ sunscreen and lip balm - UV index reaches 8+ at altitude above 3,000m (9,843ft), reflection off snow/salt increases exposure

Insulated water bottle - prevents freezing during Altiplano nights dropping to -10°C (14°F) and keeps drinks cool in Amazon heat

Quick-dry pants and shirts - morning dew and afternoon showers require fast-drying synthetic materials over cotton

Warm sleeping bag liner rated to 0°C (32°F) - hostel blankets insufficient for mountain towns and camping tours

Power bank 20,000mAh minimum - remote areas have limited charging, cold weather drains batteries 40% faster

Headlamp with red light setting - essential for pre-dawn Machu Picchu hikes and Uyuni stargazing without disturbing others

Altitude sickness medication - consult doctor for acetazolamide prescription, essential above 3,500m (11,483ft)

Packable down jacket - weight/warmth ratio crucial for varied elevations, compresses small for tropical segments

Insider Knowledge

Book accommodation in Patagonia immediately - many estancias and refugios close May 1st and won't reopen until October, creating artificial scarcity in late April

Amazon lodges offer 'dry season transition' discounts in April - same wildlife experience as peak dry season but 30-40% cheaper rates before May price increases

Harvest season workers in wine regions often share free tastings and meals - arrive at vineyards between 6-8am when picking crews gather for authentic local interaction

April marks the last month for reliable Uyuni salt flat mirror effects - May onwards brings true dry season with white salt surface but no reflections
